HARTFORD -- A judge's order sealing search warrants in the investigation of the Dec. 14 massacre at Sandy Hook Elementary School is scheduled to expire on Thursday, but whether the information they contain will remain secret or be at least partially disclosed remained uncertain on Monday.

The only thing clear, according to Danbury State's Attorney Stephen Sedensky, is that the search warrant affidavits and an inventory of items that investigators found in the cars and home of gunman Adam Lanza and his mother Nancy will not be made fully public.

"I am going to be filing something with the court on or before Wednesday," Sedensky said, an indication that he will either seek a continued sealing of the documents or ask Judge John Blawie for a redaction of information he doesn't want released.

Should Sedensky take no action, a move he specifically ruled out, all the papers would become public record.

The 20-year-old Lanza killed 20 children and six adults in a five-minute rampage at the school before committing suicide as police closed in.

The five warrants covered the search of the Lanzas' Yogananda Street home, where Lanza murdered his mother, the car he drove to the school, and his mother's vehicle, which was parked at the house.

Sedensky did file a motion on Monday objecting to a request by The News-Times and a half-dozen other news organizations seeking to intervene should he seek an extension of the 90-day sealing order imposed by Blawie in December.

The media groups claim that disclosure of the documents would not impact the investigation, because there are no criminal prosecutions that would be disrupted or delayed if the information were released, and argued they have a "legitimate interest" in the investigation, because they are representatives of the public.

But Sedensky said that the motion is premature, because there is no pending case in which to intervene, and that an ongoing criminal investigation is not subject to disclosure under the state Freedom of Information Act.

But state Senate President Pro Tempore Donald E. Williams Jr. doubts that anything will change the nature of the state and national debate on gun control.

Williams, D-Brooklyn, said that a Friday meeting with Kane and Sedensky yielded no new information for House and Senate leaders negotiating what they hope is a national response to the Newtown murders.

But he believes that some details will emerge when the warrants expire and Sedensky decides what information should and should not be kept secret, pending the active investigation that is expected to last into June.

"What he said was that he expected that there would be new information of interest to us released at the end of the day Wednesday, going into Thursday, when the warrants and returns from the warrants are released," Williams said of Sedensky.

There is still no bipartisan agreement on legislation that could be fast-tracked through the House and Senate and with major Jewish and Christian holidays this week, a possible debate and vote will be pushed off until at least next week, Williams said.

Last week, State Police came under fire from lawmakers, including Williams, Senate Minority Leader John McKinney and House Minority Leader Lawrence F. Cafero Jr., over reports that details of Lanza's plans, including a large spread sheet of international mass shootings, were revealed in police-related seminars in New Orleans, Las Vegas and at Foxwoods in Connecticut.

"It was an opportunity for us to ask questions, but we were not presented with any new information," Williams said in the Legislative Office Building of the one-hour meeting with the prosecutors.

"There's nothing he told us that we didn't already know," House Minority Leader Lawrence F. Cafero Jr., R-Norwalk, said Monday, adding that Sedensky has until Wednesday to decide whether to continue sealing the active warrants, release the warrants for public consumption or approve a partial release.

"Certainly the whole reason for my initial request was to see if there was any information they should share with us," Cafero said in an interview. "I wanted to know things like whether the gunman had attempted to buy ammunition and none of that was forthcoming."
